TRANSCRIPT
Lifting Beams & SpreadersNobles are at the forefront of lifting and spreader beam design. In addition to our growing range of standard products a large number of the spreader/lifting beams manufactured by Nobles are purpose built.
Cost, Ease of Use, Stability & HeadroomGenerally a higher cost beam will result in very good ease of use and long life while the availability of headroom greatly affects the stability of the lift. Nobles engineers have the expertise and experience to provide the best solution for any given lifting/spreader beam application.
Beam Types:
1. Basic Lifting BeamHas a centre lifting lug at the top to accommodate a crane hook and has a bottom lug at each end for connecting slings or in some instances for hooking directly to the load.
2. Basic Spreader BeamLiterally “spreads” a two legged top sling. A spreader beam has better stability than a lifting beam and a higher potential capacity for a given size of steel section used.
3. Combination BeamThis beam is a combination of (1.) & (2.) and offers the versatility of a dual purpose beam.
Other TypesThere are, of course other types of beam, most of which are adjustable versions of the basic three. Other common types worth considering are X-beams, spreader frames and H-beams.

Lifting Stability is a function of:
1. The lifting beam’s height (A).
2. The centre of gravity (G) in comparison to the lower hanging points (B).
3. Lower slings as short as possible to avoid movement.
4. The shape of the trapezoid made by the lifting beam, slings and the load.
Where (B) is lower than (G), (A) must be longer than (B)
